A 25 degree angle is waaay too steep for a good edge. Otherwise, no quibbles. Good quiz. And yes, you can pass a knife safely with an open blade. Knife safety is knife safety, whether it is an open folding knife or a big butcher knife or a locked Opinel. See you on the trail.

I figured I knew the answer, but I never close a knife with the palm of my hand. When your palms are big and the knife is small, fingers are easier to keep safe then the palm at the tip of your knife. Trust me, doesn’t feel good.
